FEEDING MECHANISM.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application as September is 1916. Serial No. 120,800.

States, residing at Goldwater, in the county.

of Mer er and State of Ohio, have invented certain new and useful improvements in Feeding Mechanisms, of which the followin r is a specification.

his invention relates to mechanism for operating the conveyer of fertilizer distrihu; ters, and has for its object the provision of a simple, compact and ellieient mechanism whereby the conveyor apron will he -operated intermittently so as to carry the distributing cylinders. A further ohjeet of pa'nying, drawings and consists in certain novel features which will he hereinafter lirst fully described and then more. particularly pointed out in the claims following the description. v

In the drawings:

Figure 1 is a side elevation of our improved mechanism;

Fig. 2 is a detail section on the line 2-42 of Fig. 1.

Referring particularly to the drawings, the reference nmneral 1 indicates a portion of the wagon bed in which the fertilizer is loaded and through whiehit is led to the heaters or distributing cylinders. A portion of theilower run of the conveyor chain is shown at 2, and 3. designates the rear axle on which the ground wheels are loosely mounted and which is actuated hy said ground wheels through the well-known escapenu-ait device, a portion of which is shown at 4'. The shalt oi? the. rear roller which supports and :u'tuates'the conveyor is shown at 5 and upon said shalt is seeured a.

ratchet wheel (3. An angle lever 7 is looselymounted at its angle or bend. upon the shaft 5 and one arm 8' of said lever extends upwardly'froin the said shaft while the other arm 9 ol the lever extends forwardly in a general direction toward the -axle In the forward end of the, arm 9 mounted a pin 10 upon which is pivoted a pawl 11 which extends upwardly and somewhat rearwardly from the pin 10 to engage the ratchet wheel The invention is illustrated in the tltftjtllll.

as cle'arly shown. -i\ hraeket 12 is secured to'the si'deof the wagon hed l, and is construeted with outstai'lding studs. 11-; upon which are pivotally mounted does 1} which extend rem'wardly from the l'tfillt't'll\'(HllHlH .so as to overhang and rest upon theratel'iet wheel 0 .andengage the teeth ol' the same to prevent haekward movement thereof. A roller 1:7.is mounted upon the pin lU and this roller is disposed in the path of move mentolf a four-armed rain it which is se cured upon the axle 5 in any desired manner and has its eam surl'ares so disposed that. when the machineis moving forwardly, the several cam arias will ride up against the roller 15 and lift the same and the arm 9 of the lever 7, therehy eausing' the pawl-ll to exert a lifting action upon the ratchet wheel 6 to partly rotate the same and' transmit movement to'the eonveyer. Upon the extremity of the arm .H of the lever 7, is loosely mounted a sleeve'li' 'througl-i whieh passes an adjusting 'rod 18' which; is matrolled through a hand lever at. the frontend oi the machine. Upon the said adjusting, rod, wesecure a stop collar 19 which is die posed near and in advance of the sleeve 17.

As the machine moves over the ground, the cam arms 16 will successively move upward-ly under the roller-15 and lift the same and the front end ol' the 'lever 7 thereby causing the pawl 11 to actuate the ratchet wheel, as he'l'ore. stated. is the lever 7 swings about the. sha l't as its fulermfn, the

sleeve 17 will he moved rea-rwardly and the said sleeve should he so mounted upon the lever and of such size relative to the adj nsting rod 18 that the. movement will not he impeded.

connected therewith will cause the same to at once swing downwardly, and it will 'he' noticed that the entire, weight of the. lever is in advance of its fulcrum or'the shaft 5. As the lever moves downwardly, the sleeve 17 will, he. carried forwardly and will in1-- pinge. against the stop collar It) so as to ur- As the cam arm clears the roiler 15 the weight of the lever 7 and the parts movement imparted to the lever. by the cam will be reduced. In this manner the con veyer apron may be given any desired feeding movement and by moving the adjusting rod 18 rearwardly and setting'it at the rear limit of its movement, the lever may be held in such position that it will not be actuated at all by the cams. may then be drawn from field'to field withlizer, as will be readily understood.- If the machine be at rest, the remnants of the load may be discharged by reciprocating the rod 18 so as to oscillate the lever 7 by alternately pushing the sleevel'? rearwardly and then permitting the weight of the parts to bring it forward.

Our improved mechanism is exceedingly simple iii the construction and arrange-- ment of,its parts and is' not apt to get out of order. Theoperation of the same is direct and posit'- ,e and does not'require the ap lication of a large amount of power;

aving thus described the invention, what is claimedsas new is: In a mechanism for the purpose set forth, the combination of a conveyer'shaft, an axle disposed in advance of saidshaft, a

I ratchet wheel secured on the shaft, an angle lever fulcrumed upon the shaft and having one arm extending in a eneral direction toward the axle, a pawl plvotally mounted-at the forward end of the ratchet wheel, a

cam on the axle acting The machine outcausing any distribution of the ferti-- sleeve mounted 100 the lever and engaging on the forward end of the .lever to impart movement thereto and means acting upon the upper arm of the lever to regulate the, throw.

2. In a mechanism for-the purpose forth, the combination of aconveyer shaft, a ratchet wheel secured on said shaft, angle lever mounted loosely on the shaft and having one arm extending forwardly therefrom and another armextending up wardly therefrom, an axle, acam on the axle adapted to act upon the forward end of the lever, a pawl carried by the forward end of the lever and engaging the ratchet wheel,'a ly upon the upper end of the upwardly extendin of the lever, an adjusting rod "exten mg throu h said. sleeve, and a stop collar- 011;" said r0 in advance-of and adjacent the said sleeve.

,3. In' a mechanism for-the purpose set forth, the combination of a conveyer shaft, an axle disposed in advance of said shaft, a ratchet wheel .securedon the shaft, a lever fulcrumed on said shaft [and extendin forwardly therefrom,a pivot pin fitted 1n the forward end of the lever, a pawl mounted on said pin and engaging the ratchet wheel, a roller also mounted on said'pin and a cam secured upon the axle and arranged to move upwardly-against said roller.

In testimony whereof we aflix our signatures.
